LUB RICATOR.

Specication of Letters Patent.

Patented Aug. 11, 1908.

Application led June 6, 19706. Serial Ilm-320,422.

To all. whom it may concern:

Be it known that I, JOSEPH L. NEHRIG, citizen of the United States ofAmerica, residing at Ardara Station, in the county of Westmoreland andState of Pennsylvania, have invented certain new and useful Imrovementsin Lubricators, of which the folowing is a specification, referencelbeing had therein to-the accompanying drawing.

This invention relates to certain new and useful improvements in vehiclelubricators, and the invention has for its primary object the provisionof novel means for equally distributing a lubricant overthe surface of aspindle or axle stub.

Another' object of this invention is the provision of novel means forretaining a quantity of lubricating oil in close roximity to the hub ofa wheel, whereby tliie spindle or axle upon which the wheel is journaled may be lubricated at all times.

A further object of this invention is to provide a lubricator forvehicle wheels which will be 'extremely simple in construction, strongand durable, comparatively inexensive to manufacture, and highlyefficient for the purposes for which it is used.

With the above and otherfobjects in view, the invention consists in thenovel construction, combination and arrangement of parts to behereinafter more fully described and claimed.

Referring to the drawing accompanying this application, like numerals ofreference designate corresponding parts throughout the several views, inwhich zM Figure 1 is a longitudinal sectional view of the hub of avehicle wheel equipped with my improved lubricator, and Fig. 2 is across sectional view of the same.

In the accompanying drawing, I have illustrated a conventional form ofvehicle wheel hub l having a plurality of spokes 2 arranged therein. Myinvention resides in providing the hub with a sleeve 3 having mteriorlyspirally arranged grooves 4 formed therein. The sleeve 3 servesfunctionally as a bearing sleeve for the spindle or stub of an axle (notshown), and is used in lieu of the ordinary bearing sleeve of a hub.

Mounted in the hub l between two of the spokes 2 thereof is a radiallydisposed tubing 5, the inner end of which is threaded into the sleeve 3,as at 6, and communicates with one of the grooves thereof. `The outerend of the tubing 5 is threaded, as at 7 and is provided with aconventional form of lubricating receptacle 8 having a cap 9 and aplunger l0 arranged therein.

In the lubricant receptacle 8 is placed a suitable lubricating oil,which is fed to the groove 4 of the sleeve 3 through the tubing 5, andthe arrangement of the grooves is adapted to convey the lubricant overthe entire surface of the s indle or stub of an axle mounted therein, tus equally distributing the lubricating oil and providing anonfrictional and easy-running engagement of the hub upon the spindle.

The sleeve 3 is preferably constructed of4 strong and durable metalhaving suflicient wearing qualities to withstand the rough usage towhich it is subjected and I do not care to confine myself to the type oflubricant receptacle used in connection with said sleeve.

What I claim and desire to secure by Letters Patent, is z- Thecombination with a wheel hub having an opening with the ends of saidopening of greater diameter than the intermediate portion and said hubfurther provided centrally thereof with a radially extending aperture,that portion of the opening of smaller diameter being of a lengthgreater than the portions of the opening of greater diameter of a sleevemounted in said hub and of a length equal to the intermediate portion ofsaid opening, said sleeve further provided with a continuous spiralgroove extending from end to end of its inner face and said sleevefurther having centrally thereof a recess, with the bottom of the recessat a point removed from the inner face of the sleeve, the bottom of saidrecess provided with an opening communicating with said groove and theside wall of said recess being screw threaded, said recess forming acontinuation of and of the same diameter as the aperture in the hub, atubular member extending through the aperture in the hub and abuttingagainst the said member and engaging the screw threads 10 bottom of saidrecess, said member of a upon said end. length to project from the outerface of the In testimony whereof I aix my signature hul?1 and rrovied onits innerhenl with pe- Vin the presence of tWo Witnesses. 5 rip eratirea s engaging' Wit t e tirea s of said recess and saidbmember furtherhav- JOSEPH L' NEHRIG ing that end Which projects from the outerWitnesses: A face of the hub screw threaded, and a lubri- MAX H.SROLOVITZ, cant reservoir mounted on the outer end of E.
